Do you want to add some bass to your ride without losing storage space? Take a look at the Kicker PT8 powered subwoofer — its heavy-duty enclosure is slim enough to fit in many locations and powerful enough to help fill in the low end of your sound system.

A perfect match
It can be tough matching subs, amps, and enclosures together. Kicker's taken the guesswork out of the process by matching a 90-watt RMS amplifier with an 8" subwoofer, and housing them together in a rugged, compact box. This way, you won't have to waste time juggling specs — just focus on enjoying your bass.

Out in a jiffy
A quick-connect power harness and removable straps make it easy to pull this sub out of your vehicle, so you can get some storage space back in a pinch. The enclosure is only 6-3/8" deep so it'll fit in a variety of spaces, while the carpet covering will protect the enclosure and your vehicle against scratches and dents.

Fantastic little subwoofef

Anonymous from Winnipeg, Manitoba on 3/6/2014

This thing is awesome have it in my 2 door hatchback CRZ. I have all the speakers upgraded JL audios C2 etc etc . Amped up and this sub can keep up with the output and does not distort unless I really crank the gain. All in all impressed. It does not however get those really really low notes that are held for extended periods of time. Regardless still an awesome product.

Great Speaker to add base to Jeep

I was looking for compact Subwoofer to add bass to my vehicle, and this did the trick. The install was easy, but I have been doing this for a long time. This Speaker Amp combo works great to give your vehicle fill bass and complete the music experience for you. What is speaker will not do is shake your vehciel or wake up your neighbors. Since is real compact you dont loose a lot of truck space for it. if you are looking for and Sub to fill the missing bass in you car and want compact size this is the way to go.

Pros:Compact

Cons:Wiring Harness. Wires could be longer (inout lines, Ground, remote) Power line was long enough

Best Option for Jeep Wrangler Trunk

If you are looking for a powered subwoofer for a Jeep Wrangler trunk (small), this is the one you want. The unit is compact, fits perfectly (leaving a small amount of area for storage in the trunk), and adds a lot of bass without becoming obnoxious.

Pros:Good bass
Compact
Fits Jeep Wrangler trunk perfectly

Cons:None

Kicker 11PT8

This sub is perfect for an extra cab Ranger, removed the jump-seat and built a bracket to solid mount the Kicker. Plenty of base, and barely have it turned up, the remote is also nice, depending on the music.

2012 Chevy Silverado Crewcab

SteveP from Sanford, NC on 9/25/2012

I have the factory stereo (not Bose) in my truck and have been pretty pleased with the sound quality. BUT, it really lacks bottom end when when I increase volume. I wanted to add bass without spending a ton of money or using a bunch of the cargo space that I bought the truck for in the first place. The common sense solution seemed to be a powered sub. However, I had my doubts about sound quality. While working in VA, I decided to drive the 90 miles over to Charlottesville and check out the retail store. Jason S. was extremely patient and helpful in making a decision. Of course, this is no surprise to any regular Crutchfield customer. The Kicked 11PT8 turned out to be exactly what I was looking for. Fits perfectly under my rear seat and I can either stand it up or simply unplug and remove it if I need the cargo space. Its a great compliment to my factory unit and really easy to install. If you're smart about routing the wiring, you'll have plenty (I had more than I needed on all wires). It sounds great and can be adjusted with the wired remote. If you're into hiphop and want to rattle the change in other peoples cars, this is NOT what you want. But if you want to fill your own space with great sound, you wont regret buying this sub.

Pros:Great price, simple to install and great sound. Add in Crutchfield's customer service and its a no brainer.

Cons:Haven't found one yet.

Great Product!

Nat D. from Hattiesburg, MS on 4/29/2012

Fits perfect in my '02 Nissan crew cab. Would recommend to others!

Pros:Sounds great, easy to install.

Cons:Wiring for power and sub not long enough for most cars.

great value/sound

Unit was pretty simple to install. Only gripe is that it should have come with master sheet since it has speaker level input option and I had to extend several leads on the factory harness. Has about the right amount of bass you would expect. This unit fits flat under the back seat of my '10 Tundra double cab. This sub has a hi/low input option so you can connect it speaker level on a factory radio or line level on an after market unit with preamp outputs. You do not need a line level converter.

Pros:Price, sound quality, compact size

Cons:Length of some leads on harness

Perfect

I have a jeep wrangler, and with the top down and large tires, the road noise is LOUD! The little 4" speakers were bottoming out because i had to turn them up too much. With limited space and not wanting to have too much money invested (its easy to break into a jeep) This speaker/amp is awesome. I took the bass out of the small speakers and use them for highs and mids only. All the bass comes out from this speaker and it sounds great!! Even at 70 mph them system sounds great! Note: dont forget to buy the RCA converter!

Features

Amplifier: The power output from the built-in class-D
amplifier is 90 watts RMS @ 14.4 volts with no more than 1% THD (100 watts RMS @
14.4 volts and 10% THD).

Signal Input: The signal input wires on the included harness can be
used with a speaker level or line level signal. Standard speaker wire is used in the harness,
so an RCA to speaker wire adapter is needed when using a line level signal (item number
20609ZISL, sold separately).

Low Pass Crossover: The amplifier's low pass crossover point is
continuously variable from 50 to 120 Hz; the crossover slope is 12 dB per octave.

Subsonic Filter: In addition to the low pass crossover, the
PT8 features a 24 dB/octave subsonic filter fixed at 25 Hz. Ultra-low frequencies
that cannot be reproduced by a subwoofer do not become sound, but unnecessary
oscillations that cause distortion. These frequencies also waste amplifier power
and can damage the speaker. The built-in subsonic filter removes the frequencies
below 25 Hz to improve the sound quality by eliminating harmful distortion.

Status Indicator Light: There is a status indicator LED on
the control panel on the left side of the enclosure; it lights green to indicate
that the amplifier is turned on and operating normally and lights Red to indicate
the amplifier's protection circuitry has been activated.

Remote Bass Level Control: The included remote bass level
control lets you adjust the output level of the amplifier from anywhere in the
vehicle. A 20' cable is included and when it's plugged in, the gain control on
the side of the enclosure is bypassed. The remote bass level control can be
mounted under the dash with the included mounting hardware, it has the
following dimensions:

Width: 2.215"

Height: 1.193"

Depth: 1.718" (3.076"
including the knob and cable)

Controls: All the PT8's controls and connections are located
on the left side:

Auto Turn-On: two position switch; choose +12V
(amp turns on when +12 volts is applied to the remote turn-on wire)
or DC Offset (amp turns on when a 6 volt surge is detected from a
speaker-level source on the signal inputs; in this mode the amp's
remote turn-on wire acts as a +12 volt output to turn on another
component)

Input Level: two position switch; choose Hi
when using a speaker level input, Lo when using a line level input

Phase: two position switch, the sub's phase
can be easily inverted; 0° or 180°

Gain: rotary knob; continuously variable from
125mV to 5V when the Input Level switch is set to Lo, 250mV-10V when
the Input Level switch is set to Hi

Remote Bass: 3.5mm mini-jack for use with the
included remote bass level control

Fuse: a single 7.5 amp ATO style fuse protects
the amplifier

Wiring Input: Molex plug for use with the included
power/ground/remote turn-on/signal input harness; the wire length varies
by function:

Ground: 18"

Signal Input: 16'

Power: 19'

Remote Turn-on: 20'
